PartitionParserTests fixes

testFullPartitionConfigurationWithMapperSuppliedProperties
* remove assert on PartitionMapper.name as PropertyPartitionMapper is used and
  PartitionMapper.name does not get populated.

testFullPartitionConfigurationWithHardcodedProperties
* when run as part of the suite, the static fields name was populated by another test case.
  add explicit reference and hardcoded property to job def
